The radar

The Columbus AFB radar (KGWX), 53 km from the middle of the area, began a volume at 00:20 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Little Rock, AR (KLZK), launched 00:00Z, 0.3 hours before the alert went out and 131 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Mar 31, 3:15 PM CST, 3 hours 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
315 PM CST FRI MAR 31 2006

.DISCUSSION...

SCATTERED SHOWS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
DURING THE HEATING. ATMOSPHERE IS WEAKLEY CAPED AND MODERATE
INSTABILITY WITH CAPES AROUND 1000-1500 J/KG ARE OVER THE REGION.
A WEAK SURFACE COLD FRONT EXTENDS FROM NEAR POPLAR BLUFF MISSOURI
TO NEAR FORT SMITH ARKANSAS. STORMS HAVE BEEN SOMEWHAT STRONGER
NEAR THE FRONT WHERE WEAK LARGE SCALE FORCING ASSOCIATED WITH THE
FRONT HAS AIDED THE CONVECTION. THE FRONT IS EXPECTED TO STALL
OUT OVER THE REGION THIS EVENING AND BECOME ORIENTED WEST/EAST.
THERE REMAINS A SLIGHT RISK FOR SEVERE WEATHER OVER THE REGION
WITH THE MAIN THREAT BEING LARGE HAIL. LOW LEVEL SHEAR
VALUES ARE SOMEWHAT IMPRESSIVE (0-1KM HELICITY BETWEEN 100-150
M2/S2) AND AN ISOLATED TORNADO CAN NOT BE RULED OUT. THE AREAL
COVERAGE SHOULD DIMINISH LATER THIS EVENING AS THE HEATING OF THE
DAY IS LOST. HOWEVER THE THREAT FOR CONVECTION WILL PERSIST AS
LONG AS THE FRONT IS AROUND. 18Z NAM ALONG WITH AFTERNOON TRENDS
WHICH SUGGESTS A CONTINUED SLOW SOUTHEASTWARDPROGRESSIONN OF THE
FRONT. AS A RESULT AM COMPELLED TO CONTINUE CHANCES ALL NIGHT OVER
THE ENTIRE REGION. ONGOING SATELLITE TRENDS INDICATE PARTLY CLOUDY
CONDITIONS TONIGHT AND HAVE LOWERED FORECAST TEMPS TO NEAR
GUIDANCE DUE TO LESSER THAN ANTICIPATED CLOUD COVER.

THE FRONT SHOULD STALL NEAR THE TN/MS BORDER TOMORROW. CHANCES OF
THUNDERSTORMS WILL CONTINUE ONCE AGAIN TOMORROW...MAINLY AHEAD OF
THE FRONT IN THE WARM SECTOR. EXPECTING PARTLY CLOUDY CONDITIONS
ONCE AGAIN AND HAVE BUMPED UP HIGHS INTO THE UPPER 70S. THE FRONT
SHOULD SURGE NORTHWARD AS A WARM FRONT SATURDAY NIGHT THUS
CONTINUING SLIGHT CHANCES. ON SUNDAY...A PAIR OF SHORTWAVE THROUGHS
AND ANOTHER COLD FRONT WILL INFRINGE UPON THE REGION. THE INITIAL
SHORTWAVE IS EXPECTED TO MOVE THROUGH DURING THE MORNING HOWEVER
IT IS EXPECTED TO OUTRUN THE SURFACE COLD FRONT. SO EXPECT
CONVECTION TO WEAKEN AS IT APPROACHES THE AREA. BY LATE SUNDAY
AFTERNOON AND ESPECIALLY SUNDAY EVENING...THE SECOND SHORTWAVE IS
EXPECTED TO PHASE WITH THE COLD FRONT. THIS WILL BRING A MUCH
BETTER CHANCE FOR STORMS TO THE REGION. GOOD INSTABILITY IS
EXPECTED TO BE IN PLACE WITH CAPES NEARING 2000J/KG AND 0-1KM
HELICITY IS GREATER THAN 200 M2/S2. THIS FRONT LOOKS LIKE THE
BETTER CHANCES FOR SEVERE WEATHER OVER THE WEEKEND. CONTINUE POPS
INTO MONDAY DUE TO TIMING UNCERTAINTIES.

UPPER RIDGE AND ASSOCIATED HIGH PRESSURE SHOULD RESULT IN DRY
CONDITIONS THROUGH END WEEK. THEN ANOTHER UPPER TROUGH AND COLD
FRONT WILL ARRIVE RESULTING IN MORE CHANCES FOR THUNDERSTORMS.
